Saw some guy on ebay selling a bunch of NES cart boards as "precious metals" (meaning he thinks one should scrap them) not games.
From the chip IDs I could read there was a couple Bases Loadeds in there.
Other confirmed games Othello for NES and I think NCAA Basketball for SNES.
Probably at least a Super Mario Bros and a Duck Hunt (but not SMBDH).
Another PCB ID I could read (but not the game ID) meant it (most likely) was a To The Earth, but could be Burai Fighter or Lolo 2.

Wouldn't mind Revelations: The Demon Slayer getting released in Europe one day.
And while i'd like to have the Donkey Kong Land games on my 3DS i'd probably wait for a discount since i've got all the originals.
